Given two positions on a map, draw a straight line between them when a condition is met

Hello, I am simulating a cellular cell with N users whose positions x,y are generated randomly. I have a matrix L (NxN) where L(i,j) (the indices i and j represents two users) could be zero or have a different value. I would like to plot the positions ( I ve done it) but also to plot a line (a link) between the users i,j whose L(i,j) is different from 0.. How can I?

Hi,

Assuming that you have properly declared and defined posx and posy vectors (containing x and y coordinates of users) and L matrix (as told in the question), you may find the below attached code helpful:

figure(); 
for i =1:size(A,1) 
    for j =1:size(A,2) 
        if A(i,j)~=0 
                plot(  [posx(i) posx(j)],  [posy(i) posy(j)] );
                hold on; 
        end 
    end 
end 
hold off;
